The general object of this invention is to provide a washing machinewhich shall be entremely simple and compact in construction and whichshall be of relatively small a size, thereby adapting it particularlyfor use in washing the soiled garments of babies and children. v

Stated more in detail, objects of the invention are to provide avertically disposed tub w or container removably ymounted on anoscillating support to provide novel means for oscillating the supporton which the container is removably mounted; and to provide a novelconstruction of container which in operation l5 will thoroughly agitatethe Water and the articles being washed and cause them to be cleanedwith great rapidity.

Other objects of the invention relate to details of construction and tonovel combina- 20 tions and arrangements of parts all of which will beclear from the description ',of the invention to follow.

In the preferred embodiment of the invention my improved washing machinecom prises a base having a motor pivotally mounted at its lower endthereon and provided with mechanism for causing the motor to beosoillated back and forth as its shaft rotates, in the manner of anoscillating fan. The base preferably forms the bottom of an enclosure orcasing on the top of which lis provided a suitable ball bearingsurrounding an opening for a stub shaft, `the lower end of which isnon-rotatably engaged with the top of the motor. The said stub shaft ispreferably formed integral with a circular support from the center ofwhich it projects downwardly. Said support is provided with a pluralityof apertures and the container is provided on its bottom with acorrespondingnumber of studs 4which fit into said apertures, so that asthe said support is oscillated by the corresponding movement of themotor, the container will have imparted to it a corresponding motion.

' In the drawing Fig. 1 is a plan view, partly broken away, of myimproved washing machine; Fig. 2 is a View partly in verticalelevationand partlyv in section of the same;-Fig. 3 is a top `plan view of thesupport for thecointaner; Fig.- 4

is a perspective view of the agitator mounted within the tub; Fig. 5 isa section plan view ou the line 5*5 of Fig. 2; and Fig. 6 is a sectionalplan view on an enlarged scale, illustrating by dotted lines the pathsof movement of certain partscausing the-oscillation of the motor.

Referring now to the drawing, tlie numeral 1I indicates the 'base of themachine which, preferably, is in the form of an enclosed structurehaving a bottom 2 and a top 3. The bottom 2 on its upper side isprovided with a central step-bearing'l and the" top 3 is provided witha` central bearing 5 on its underside and with a ball bearing 6 on itsupper 65 si'de, said bearings accommodating a stub shaft 7 passingthrough them and projecting downwardly from the center of the undersideof a circular plate oi` support 8. This plate or support is designed tobe oscillated in a manner and by means presently to bedescribed. Numeral9 indicates the container, which, as shown, is vertically disposed andusually constructed pf sheet metal, such as, tin, copper or the Vlike'.75

The support 8, as shown by Fig. 3. is provided with a series 0fapertures 10 which, as shown, are three in number; an d the container 9is provided on its under-side with a corresponding series of studs l1which are adapted 8O to litsnugly in the apertures 10. lhen thecontainer isthus positioned on the support 'S it will movewith'the`support as the latter is oscillated, as will be understood: Thecontainer 9 is preferably provided with a bail. and has a removableclosure 13 providedwith a central handle 14 for manipulating it.l

Within the container I .mount means for causing agitation of the waterand pf thc articles being washed in the oscillation of said container.This means is shown in Fig. 4 and consists of a triangular-shaped memberwhich is secured along one of its sides to the bottom of the containerand has its other side projecting upwardlyl along the wall of 9" the'container and in contact therewith. Ono Way 0f forming thisagitatingdevice will be apparent `from Fig. 4, and consists in bending asheet ofmet'al upon litself to provide a triangular body portion -15 andflanges 16 100 v vertical center.

projecting laterally from one side thereof. These flanges are providedwith apertures 17 by means of which the agitator, indicated in Fig,2generally by the numeral 18, may be secured -to the bottom of thecontainer. When so positioned, the -hypotenuse of this triangular figurewill extend from about the center of the bottom of the container to apoint located at something less than the distance from the bottom of thecontainer to its It will of course be understood that these dimensionsof the agitator may be varied, if found desirable.

For producing` an oscillating movement of the container I provide anelectric motor 19 having on its under side a boss 20 which is seated ina step bearing 4, the boss being free to turn in said bearing. On itsupper side the casing of the motor is'provided with a hollow boss 21,the openingr in which is non-circular and receives the similarly-shapedlower end 22 of the stubshaft 7. At one end the motor is provided with acasing 23 in to which, as shown by Fig.` 5, extends the motor shaft 24,the outer end of said shaft having a bearing in the end wall of casing23 as shown at 25. Within the casing 23 shaft 24 is provided with a worm26 which engages the teeth of a worm-wheel 27, horizontally disposed andmounted on a vertical shaft 28; and mounted on the lower end of theshaft 28 is a crank disc 29 on the under-side of which is eccentricallysecured one end of a. Pitman-.rod 30, as indicated at 31 in Fig. 6, theother end of which is pivotally mounted at one side of the step-bearing4, as shown at 32 in said figure.

It will be apparent th at as the motor shaft is rotated the crank disc29 will be caused to rotate by the engagement of the worm wheel 27.withthe worm 26, the shaft 28 being fast with said worm-wheel and said crankdisc;

and as the inner end of rod 30 is fixed against all but pivotal movementon the step-bearing 4, the motorrwill first be moved in one directionuntil the pivotal connection 31 on disc 29 has passed a dead center, andthen in op osite direction, and thus be continuously7 osci lated on itscentral pivotal bearing 20. This movement of the motor will be impartedto the stub shaft 7, support 8 and container 9 mounted on said support,with the result that the water will be severely agitated, in a wellknown manner, by the agitator 18. This movement of the water over andthrough the articles being washed, together with a similar, but somewhatless degree of movement of the articles themselves, results in a veryrapid and eflicient cleaning of such articles. Inpractice. the containerhaving therein a number of articles equivalent in bulk to about twolinen sheets will effectively wash the articles iri about l5 minutes.

I claim: f
